 rpm Ok I looked but could not find what I was looking for
I done a up grade on a 36 prodrive head cam piston carb ect.
The rpms are 1200 in neutral and 1100 in gear and tops out at 4200 is that good ?
I was thinking getting 4700 rev limiter rpm but It took all I could to get it to hit the factory rev limiter. Is this normal ? The speeds are one guy 30 two 25 THANKS FOR ANY HELP

Re: rpm something is wrong with those mods you should be running better than that.

Re: rpm How was your trim. That has a lot to do with it. I run 4650 no problem with the mods I have even with a load and new prop.

Re: rpm Something isn't set right. I could turn 4600 with a load with heads, cam, carb, and exhaust.

Re: rpm I have a stage one and I am all over 4700 rev limit. So you should be doing way better than that with those mods

I cant make it hit that trim up but the throttle is all the way , It has new prop , Maybe I messed up on the numbers. I going to take it out again and redo it what numbers are good with the factory rev thanks sorry for all the ??

Re: rpm You sure your governor is locked out maxed? Something is wrong if you can't get over 4300.
I have an 1851 Excel and ran 4300 with 5 people with a hammer prop this weekend.
